WATER-CLOSET-SEAT-OPERATED VALVE.

Specification of Letters Patent.

Patented Mar. 2?, 1917..

Application filed February 16, 1915. Serial No. 8,482.

To all whom it may concern:

Be it known that I, GEORGE D. ENDY, a citizen of the United. States, residin in the city and county of Philadelphia, tate of Pennsylvania, have invented a new and useful Water-Closet-Seat-Operated Valve, of which the following is a specification.

My invention relates to an improvement in a water closet flush tank, and consists of means whereby when the seat of the bowl is occupied, the valve of said tank is primarily engaged, and then when said seat is relieved of the occupant thereof, said valve is fully opened, causing thereby the refilling of the tank, causing the primary-engaging member of the valve to return to its normal position.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be va ried, as long as they are included in the scope of the claims.

Figure 1 represents a vertical section of a flush tank for a water closet embodying my invention including a side elevation of the bowl and appurtenances.

Fig. 2 represents a vertical section of the tank, showing certain parts in different positions from those in Fig. 1.

Fig. 3 represents a vertical section of the tank on an enlarged scale showing certain parts in different positions from those in Figs. 1 and 2.

Similar numerals of reference indicat corresponding parts in the figures.

Referring to the drawings,

1 designates a flush tank, and 2 designates the discharge pipe thereof, the upper end of said pipe forming the seat 3 for the valve 4, the latter having fitted freely in it the vertically arranged rod 5 which is connected by the bar 6 with the interior of the pipe 2, whereby said valve may be guided in its opening and closing motions, the stem 4 of said valve having on its upper end the conical heads 7 which form at their places of connection the shoulder 8 which is adapted to be engaged by the nose 9 of the supplemental lever 10, which of the form nf an elbow depends on and is pivotally mounted from the yoke 11, as its fulcrum, said yoke being adjustably connected by the screw 12 with the rising and lowering or sliding bar 13, said screw having thereon the nut 14 for evident purposes. V y

The bar 13 is guided in the boss 15 which is connected with the upper portion of the tank 1 by the angular hanger 16 which is attached to the latter by the bolt 17 or other suitable means, said bar 13 being pivotally connected with one end of the swinging lever 18 whose bearing is on the ear 19, the latter being supported on the upper limb of the hanger 16.

The other end of the lever 18 is pivotally connected with the ear 20, which is attached to the weight 21, the latter surmounting the raising and lowering rod 22, and serving to lower said rod, as will be hereinafter again referred to, said rod being freely inclosed in the chamber 28 on the interior of the tank 1, and being extended through and below the bottom of the latter to the heel or rear end member 24 of the seat 25 of the water closet bowl 26, said seat having its axis on the ear 27 rising from the bowl, its normal position being slightly raised from the top of the bowl, so that when it is occupied, it will be lowered.

The heel 24 has a vertically-extending opening therein for the passage of the lower end of the rod therethrough, said end being screw-threaded and having nuts 28 thereon respectively above and below said heel, so that the latter may engage with said nuts, particularly the upper nut so that in the lowering motion of the seat 25, the heel 24 rises and presses upwardly against said nut and so raises the rod 22, and when the latter descends saidnut bears downwardly against said member and so causes the elevation of said seat, as shown in Fig. 1, said nuts 28 also serving to adjust the play of the heel 24 and consequently of the ascent and descent of the seat 25.

The portion of the rod 22 that passes through the opening in the bottom of the tank 1 is screw-threaded and has connected therewith the nuts 29 which are respectively above and below said bottom so as to act as adjusting stops for said rod and connected parts.

.Within the tank is the siphon and overflow 30 of inverted U-shape, the lower end of one limb opening into the tank 1,

' near the base thereof, and that of the other r v float 33 which 1s submerged in the water in limb being connected with and opening into the byV-pass 31, which projects from the side of the discharge tube 2 and communicates with the interior thereof below the valve seat 3 on said tube. V

Connected with the elbow lever 10 is the arm 32 to whose outer end is attached the arm 32 and the float 33. The nose of the elbow lever 10 rides downwardly upon the side of the upper conical head 7 of the body of the valve 4.- until itreaches the shoulder 8 when the float 33 causes the vertical limb of the lever 10 to turn to move said nose under said shoulder all as shown in Fig. 2,

thus grappling the stemof thevalve 4 and causing a connection of said valve with said elbow lever, the several parts retaining their position as long as the seat 26 is occupied.

7 hen theoccupant of the seat vacates the same the rod 22 is now controlled by the weight 21, when the upper nut 28 presses downwardly on the heel 2 1 and so raises the seat 25, and restores it to its normal position. Simultaneously therewith the lever 18' is operated wherebythe sliding bar rises and carries with it the elbowlever 10, and consequently the valve 4,see Fig. 3, whereby the latter is opened and the water of the tank rushes into and through the pipe 2.

. The siphon 30 also becomes operative to discharge the water from the lower portion of the tank into the pipe 2, the water thus being forcibly directed into the bowl 26 and 7 so effectively flushing the same.

' As the water in the tank lowers, the float 33 removes the nose of the elbow lever 10 p from the shoulder 8 whereby the valve de scends and closes on its seat. Then and as the tank refills the floatrises whereby the elbow lever resumes its normal position as in Fig. 1. Then the water remains in the tank until the seat is occupied again when the operations stated are repeated and the valve is opened to cause the next flushing of the bowl.

Should the water -lIlf the tank rise beyond a predetermined height the escape of the excess is occasioned through the member 30 to the pipe 2, this preventing overflow of the tank.

On the elbow lever 10 at the outer terminal of the horizontal limb thereof is the shoulder 35 which is adapted to abut against the yoke 11, as in Fig. 1, to limit the motion of said lever in order to hold the latter in position, for the subsequent engagement of its nose with the shoulder 8 on the valve stem 4* when the valx e ascends, it being noticed also that said shouldermoves from the yoke to permit said nose to engage with said shoulder as in Fig. 2, and furthermore, as in Fig. 3, to permit the subsequent disengagement of the nose from said shoulder when the float descends, the nose then moving laterally from the shoulder, whereby the valve is permitted to drop and so close on its seat 3.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a flush tank water closet, a movable seat for the bowl of said closet, a discharge pipe at the bottom of the tank, a valve for said pipe having its seat on said pipe, a stem for said valve, an oscillating elbow lever, a bearing piece for the latter, a slidable bar member adapted to carry said bearing piece, a float connected with the horizontallimb of said elbow lever, a nose on the other limb of said lever, the upper portion of said valve stem having thereon conical heads and a shoulder with which said nose is adapted to engage, and a boss on said tank, said slidable member being freely fitted in said boss and guided by the latter, means on said lever adjacent said bearing piece engageable with the latter above and below the axis of the lever on said bearing piece relatively to the different portions of said lever and means for moving said member primarily operated by said movable seat.

2. In a flush tank for a water closet, a valve on the tank, a shouldered valve stem thereon, an oscillating elbow lever having a nose on the lower end of one limb thereof adapted to engage said shoulder, a float lever connected with the other limb of said lever, a bearing piece for said lever, a slidable bar adapted to carry said means for operating said bar, and a collar on said lever adjacent to said bearing adapted to abut said bearing above and below the axis of said lever on said bearing piece relatively to the difl'erent portions of said lever.
